In this video I'll teach you how to create a real-time fisheye camera effect using vanilla JavaScript and HTML Canvas. This warping effect is done using just basic math and vanilla JavaScript. We apply this effect on a Christmas ornament to make it look like we're reflected on it. I also teach you about time complexity and code optimization.

Welcome to Lesson 8 of the Understanding AI course, where Ill guide you through the process of transforming a self-driving car simulation into an exhilarating racing game using JavaScript! In this tutorial, Ill show you how to take control of the main car while letting AI handle the others. Well implement crucial features like a countdown timer, progress monitoring, and a scoreboard for a complete gaming experience.
In our racing game, Ive made a deliberate choice to exclude collisions between cars, ensuring a fair and competitive environment. After all, who wants their AI-controlled car to be unexpectedly smashed by others on race day?
Now, fire up your JavaScript editors, as its time to dive into the world of racing game development! Join me as we code the non-collision racing experience youve been eagerly waiting for. Let the race begin, and dont forget to like, share, and subscribe for more lessons on AI and game development in JavaScript!

Welcome to the course where we build a self-driving car simulation in a virtual world. In this video Ill teach you how to add a dynamic viewport to our graph editor using basic HTML, CSS and JavaScript.
While the current editor may be great for smaller tasks, the dynamic viewport will be really useful if you want to create larger graphs that extend beyond your screens boundaries. The viewport will allow zooming and panning, just like the editing experience you find in software like Photoshop.
By the end of this tutorial, youll have the ability to work on expansive graphs with ease, making your editing process incredibly flexible. But thats not all – well also ensure that your hard work doesnt vanish into thin air. Ill teach you how to save your graph so that it remains intact even after refreshing the page.
Its time to get that birds eye view of your graphs, quite literally! 🦅 Lets dive in and make your graph editing experience more versatile and persistent.
Have Fun! :-)
